FOCT=VVARMING APPARATUS FOR BEDS.

SPECIFICATION forming part of Letters Patent lq'o. 385,865, dated July10, 1888,

Application filed October 31, 1887. Serial No. 253,858.

To (LZZ whom, it may concern;

Be it known that I, JAMES A. Lnwrs, of St. Clairsville, in the county ofBelmont and State of Ohio, have invented a new and improvedFoot-lVarming Apparatus for Beds, of which the following is a full,clear, and exact description.

lhe object of this invention is to provide an apparatus which willcontain a supply of water or othersuitable liquid, and permit and securea heating of said water, &c., and a circulation thereof through anincloscd warming chamber or casing adapted to be disposed at the foot ofthe bed, insuring a continuous operation thereof without care orattention; and the invention consists in certain constructions andcombinations of parts for operation and effect, all substantially aswill hcrei nafter more fully appear, and be pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures Figure 1 being a perspective viewillustrating the foot-warming apparatus in its dispos1t1on in relationto the foot of a bed. Fig. 2 is a central vertical section through thesupply and heating tanks of the apparatus; and Fig. 3 is an enlargeddetail view of a portion of one of the flexible liquid-conduits, to behereinafter referred to.

In the foot-warming apparatus I employ three separate receptacles orliquid-tanksrespcetively a liquid receiving or supply tank, A, aheating-vessel, l5, and a foot-warming tank, C-and the tank A restsabove and is adjustably supported from the tank 13 by means of its guideelasps a, embracing and sliding on the vertical guide, and support-rodsb, projecting above and upwardly from the tank A and held in placethereon by the setscrews (1.

The heating-tank, as shown, is of cylindrical form, and it has an innerand upwardlyextending recess, B, or rabbeted formation in its underside, within which a lamp, D, or other heater may be disposed, suchrabbeted construction securing increased heating-surface. From the tankA a hose, E, or other flexible or suitable conduit, is passed to theheating-receptacle 13, preferably entering same (No molleL) at its lowerend, and from said heating-tank. B a hose or flexible conduit, F, passesto one end of the foot-warming receptacle 0, which is indicated in Fig.1 as of an incloscd cylindrical form, intended when in use to be wrappedwith a woolen or other cloth, and from the opposite end portion of saidcasing 0 another similar hoseconnection, G, is employed extending to thesupplytank A, a free circulation being secured and permitted in andbetween said receptacles by and through said tubes E F G, such flow andcirculation being regulated by suitable cocks or valves, cfg, providedat each hose-passage.

If desired, check-valves may be employed in any or all of the passages EF G, whereby the heated water from the heating-tank may always pass toenter the said foot-warming tank and be prevented from any return flowdirectly to the said heating-tank, and to freely pass from saidfoot-warming tank to the supply-receptacle A without any return flow tothe said receptacle being permitted, and also to permit the passage ofthe liquid from the tank A to the tank B, preventing any passage orback-pressure of such liquid directly from the heating-receptacle to thetank 0.

H represents a funnel-shaped passage leading into the receptacle 0,closed by a removable ball valve or spherical stopper, H, through whichto supply the water to the apparatus, and such water when so enteredthen passes through the conduit E to and through the heating-tank, whereit becomes sufficiently heated in the transit, and thence passes to andthrough the foot-warmer receptacle 0, returning to the supply-receptacleA to again circulate as dcscribed, the head or water pressure securingthe circulation or flow, which is further insured and accelerated by theheating thereof.

lhc flexible tubular conduits F G, at their portions toward theirconnections with the foot-warmer casing, are preferably provided withshort internal re-enforcing tubular sections 70 It, as seen in Fig. 3,arranged at suitable intervals in the hose-passage, whereby any pressureupon such portions of the hose, as by the weight of the bed-clothing,will not compress the passages to prevent or retard the circulation ofthe heated water.

The heating-tank B is to rest upon any suitable support, as legs m, anda bracket,.n, is shown as being supported by said legs on which theheating-lamp may rest, and it is preferred to provide alamp-chimney ofmetal or other opaque or non-transparent material that the room may notbe lighted.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with a supply-tank and a heatingtauk having aliquid-conduit between them, of an inclosed foot'warmer tank, and aliquid-conduit leading from said heatertank to said foot-warmer tank,and a liquidconduitleading from said foot-warmer tank to saidsupply-tank, substantially as and for the purpose described.

2. The combination, with a supplytank and a heater-tank having a liquidconduit between them, of an inclosed, foot-warmer tank, and aflexibleliquid conduit leading from said heater-tank to said foot-warmer tank,and a flexible liquid-conduit leading from said footwarmer tank to saidsupply-tank, substantially as and for the purpose described.

3. The combination, with asupply-tank and a heater-tank having aliquid-conduit, E, between them, of an inclosed foot-warmer tank, and aflexible liquid-conduit, F, leading from said heater-tank to saidfoot-warmer tank, and a flexible liquid-conduit, G, leading from saidfoot-warmer tank to said supply-tank, one or more of saidliquid-conduits being provided with a regulating-valve, substantially asand for the purpose described.

4.. The combination,with asupply-tank and a heater-tank having aliquid-conduit, E, between them, of an inclosed foot-warmer tank andflexible liquid-conduits F G, provided with the rigid tubular sectionsk, leading from said heater to said warmer and from said warmer to saidsupply-tank, substantially as and for the purpose described.

5. The combination, with a heater-tank, B, having verticalsupporting-rods I), and a supply-tank, A, having guide clasps a andsetscrews d, and a flexible liquid-conduit, E, between said tanks, of aninclosed foot-warmer tank, 0, and liquid-conduits F G, leading from saidheater to said warmer and from said warmer to said supply-tank,substantially as and for the purpose described.

' 6. The combination,with a supply-tank, A, and a heater-tank, B, havinga recessed bottom, 13*, and a liquid-conduit between said tanks, of aninclosed foot-warmer tank, O, and

liquid-conduits F G, leading from said heater 8. The combination, withasupply-tank, A,

having a funnel-shaped inlet, H, and a spherical stopper,h, and theheater-tank, and a llquid-conduit between said tanks, ofan inclosedfoot-warmer tank, C, and liquid conduits F G, leading from said heaterto said warmer and from said warmer to said supply-tank, substantiallyas and for the purpose described.

9. The combination, with a supplytank, A, a heater-tank, B, and afoot-warmer tank, 0, a liquid-conduit between said sup'plytank andheater-tank, a liquid-conduit between said heater and foot-warmer tanks,and a liquidconduit between said warmer-tank and supply-tank, of a lamplocated under said heatertank, substantially as and for the purposedescribed.

10. The combination, with a supplytank, A, a heater-tank, B,afoot-warmer tank,G, and a liquid-conduit between said supply and heatertanks, a liquid-conduit between said heater and foot-warmer tanks, and aliquidconduit between said foot-warmer and supply tanks,ofalamp providedwith a non-transparent chimney located under said heater-tank,substantially as and for the purpose described.

11. The combination, with a heater-tank, B, having verticalsupporting-rods b, a supply-tank, A, having guide-clasps a, andsetscrews d, the funnel shaped inlet H,and spherical stopper h, thefoot-warmer tank 0, and the flexible conduits E F G, respectivelyleading from said supply-tank to the heater-tauk,from the heater-tank tothe foot-warmer tank, and from the foot-warmer tank to the supply-tank,each conduit being provided with a valve,and the said conduits F and Gprovided with the rigid tubular sections k, of a lamp located under saidheater-tank, substantially as and for the purposes described.
